Visit this base URL: http://linuxmint-apt.killerhorse.eu/ Looks like you will have to select a different mirror. - Cannot tell you which one, because LMDE is not my game.By the way in order to see all configured repository addresses use the command

As karlchen mentioned, there is currently no mirror service from killerhorse.Don't worry about the error message. I get that as well when trying to change mirrors via terminal.

The command to change mirrors via terminal is mintsources or software-sources, but there should be an entry at Menü > Systemverwaltung > Software-Quellen (translates into something like menu > system settings > software sources). This should let you change your sources.There has been no recent change of mint-mirrors, so I suppose it still contains rts-informatique, which stopped service yesterday but will still be on the list (won't turn up at the top though, if you choose mirror by speed).

A list of current mirrors can be found at http://www.linuxmint.com/mirrors.php (LMDE-sources at the bottom "Package mirrors for LMDE"), in case you have to change the sources file some other way.

Check whether /var/cache/apt/archives contains mintsources_1.2.4_all.debIf so, you can reinstall mintsources using synaptic. That should fix it.If it is not cached you can download it manually from http://packages.linuxmint.com/pool/main ... .4_all.deb and install with gdebi.

Forget about the error message.It's just some package complaining that the kernel version is called 3.11-2 instead of 3.11.2 or 3.11.0-2 or something like that. You can google stuff like that (or use another search engine) and find hundreds of pages, for example https://bugs.debian.org/cgi-bin/bugrepo ... bug=732136 .

What happens when you start software-sources? Just the mentioned error message without the program starting? Or does the program start but not work like you expect it to work?

im VERRY SORRY about the problems with my mirror.Everything startet with a faulty Harddisk wich was changed. Then a couple of mischances and unlucky occurrences caused the Server to be down for several Days.Now it is up and running again.Currently I'm synchronizing the mirror with one of the rsync mirrors. I will answer again if the mirror is ready to be added to the list again.
